The Germans had entrusted their secret communications to an ingenious ciphering machine the Enigma, which was portable, easily operated, and could be set up in millions of ways. The codes were used and every one was changed every 24 hours.

Dr Mark Baldwin has made a detailed study of the Enigma machine, the code-breaking work at Bletchley Park, and U-boats and has built up a unique collection of slides which illustrate the main features of those important facts of the Second World War. He has prepared an entertaining instructive show on this subject.
The show is divided into two parts. It is followed by an opportunity for questions, then a hands-on demonstration of one of the very few surviving Enigma machines.
